Vocia ® Amplifier (VA-8600c) Data Sheet
The VA-8600c is a digital networked multi-channel amplifier for use in Vocia systems. The VA-8600c is CobraNet® enabled and features eight channels of modular amplification and DSP with optional channelto-channel or device-to-device failover. It can support up to eight amplifier cards that are individually software configurable from 100–600 Watts for up to 2400 Watts of power per chassis. 70V, 100V and low-impedance outputs are software selectable per card. The on-board DSP provides comprehensive fixed-chain digital-signal processing within the device, including volume control, ducking, equalization, compressor/limiter, speaker crossover, delay, and output gain. Emergency messages for life-safety compliant systems are stored in non-volatile memory within the VA-8600c. Intuitive software provides audio system design via PC. Two RJ45 connectors on the rear panel of the VA-8600c provide redundant connectivity to control data and audio over a single Ethernet cable. As part of the Vocia system, the VA8600c meets EN 54-16 certification for facilities of all sizes.
FEATURES • Modular based design • Amplification modules have software configurable power levels/load options –8 amplification modules per frame with 100 to 600 Watts per module (maximum of 2400W per chassis) –7 0V or 100V with direct drive capability, or low-impedance (4 or 8Ω) operation –M aximum of 2400 Watts of power in a device • Failover capability between channels and amplifiers • Local non-volatile storage of emergency messages • LED Indication: – Amplifier failure – Clip present – Fan stuck-rotor – Heat sink temperature fault – Signal Peak – Signal present
• Software Monitoring Features: – Amplifier failure – Excessive clipping – Fan stuck rotor – Heat sink temperature fault – Peak present – Short circuit on output • Software-configurable signal processing including volume control, filters, compressor/limiting, delay, speaker equalization, and output sensitivity • CobraNet audio and control data over a single Ethernet cable • Dual Ethernet ports for redundancy • Heavy duty removable terminal block connectors for speaker line connections • Rotary switches for unit identification • Rack mountable (3RU) • CE marked, UL listed & RoHS compliant • Covered by Biamp Systems’ warranty
ARCHITECTS & ENGINEERS SPECIFICATION The modular amplifier shall be designed exclusively for use with Biamp® Vocia systems. The amplifier shall be modular and support software configurable power levels/load options of 8 amplification modules per frame with 100 to 600 Watts per module (maximum of 2400W per chassis) and 70V or 100V with direct drive capability, or low-impedance (4 or 8Ω) operation. The amplifier shall provide control data and digital audio over CobraNet®. The amplifier shall provide dual Ethernet ports for redundant network connection. The amplifier shall provide frontpanel LED identification of amplifier and card failure, signal present, clip present, fan stuck rotor fault, heat sink temperature fault and provide additional software monitoring features including short circuit on output fault. The amplifier shall be rack mountable (3RU) and feature software-configurable signal processing including volume control, filters, compressor/limiting, delay, speaker equalization, and output sensitivity. The amplifier shall support channel-to-channel and chassis-to-chassis failover. The amplifier shall be EN54-16 CE certified, UL listed and shall be compliant with the RoHS directive. Warranty shall be five years. The amplifier shall be a Vocia VA-8600c. Biamp Systems 9300 S.W. Gemini Drive, Beaverton, Oregon 97008 U.S.A.
